To (@ZZ whom it may concern.-

Be it known that I, DANIEL P. KANE, of the city of St. Louis, in'the State of Missouri, have invented a certain new and useful Improve mentin Steam-Engines, of which the follow ing is a full, clear, and exact description. reference being had to the accompanying drawings, forming part of this specification.

This engine has two pistons provided with wholly independent steam-connection. working in separate and distinct cylinders in line with each other, and one pistoirrod working centrally within the other. The piston-rods are connected to a compound. crank so formed that the cranks are carried over their deadcenters. The eccentrics are upon a single hub connected to the main shaft by a sliding clutch having a toot-h engaging in one of two recesses upon the eccentric, according to the direction in which the main shaft is turning.

Figure 1 is a longitudinal section at 1 1, Fig. 2. Fig. 2 is a top View of the engine. Fig. 3 is a side view of the eccentrics.

A is the engine-bed.

B and O are two distinct engine-cylinders fixed upon the bed in line with each other,and separated by a fixed diaphragm or partition. 1). The cylinders are shown as made in one casting. In the cylinder B works a piston, E,

whose rod F passes through a. stutfing-box, G,

in the partition D.

H is a screw-gland of the stuffingbox.

I is a piston working in the cylinder 0. This piston has a tubular piston-rod, J,through which the piston-rod F passes centrally.

K is the stuffingbox, through which the piston-rod J works. The pistoirrod F is firmly connected to asliding head, L, working on guides M, that is connected by a rod, N, with a wrist, 0, upon a compound crank, O, of the main shaft P.

o is a crank-wrist set at right angles with the wrist 0 upon the crank 0, so that when one wrist is at a dead-center the other is at half-stroke, so that the rod acting on one wrist carries the other wrist over its dead-centers. The wrist 0 is connected by a rod, Q, to a wrist, R, fixed upon the side of the tubular piston-rod J. S and T are the eccentrics, secured to a hub, U, turning freely on the main desired to turn.

shaft 1, except when clutched thereto by the sliding clutch V, that works on a spline or feather, \V, upon the main shaft. The clutch has a tooth, X, that may be engaged in either of the two notches Y of the hub, according to the direction in which the engine-shaft P is "When it is desired to reverse the engine, the clutch-tooth X is drawn out of the notch Y, and as the clutch-collar V turns relatively to the hub U the tooth is forced into the other notch Y, and the movement of the valves is changed. The clutchcollar is moved along the main shaft to engage and disengage the tooth X by a lever, Z, whose forked end has studs entering a circumferential groove of the clutch-collar, as usual. The eccentric-rod i" is connected to the arm a of a rockshaft, b, that has arms c, connected by rods (1 to the ends of a cross-head, e, to whose middle the valve-rod f of the slide valve 9 is connected. The eccentric-rod T is connected to the arm h of rock-shaft 0), having an arm, j, to which is connected the valve-stem k of the slide-valve Z.

No novelty is claimed in the construction of the slide-valves, steam ports, or steam-chest. Any suitable valves maybe used to govern the entrance and exit of steam to and from the cylinder. v

. I have stated that the two crank-wrists 0 0 are set at an angle of ninety degrees, or at a right angle, to each other. This I believe to be the best arrangement; but I do not confine myself to any angle of variation. The pistonrod F is lubricated by oil fed tothe stuffing- ,box G through an oil-hole, G.

It will be seen that in my engin the cyliuders have not any connection with each other, and therefore I can supplythe steam to each piston just at the right time and "out off without affecting the other piston in the least. Thus, though the pistons are at times traveling in the same direction and sometimes in opposite directions, and at continually-vary ing speeds, yet one never acts as a clog on the other or on the main shaft, to which both of their cranks are secured.

My pistons have, as already stated, wholly independent steam-connection.

In my engine one of the pistons can be disfore, considered separately, 1' do not claim.

fl: claim as my in\'cntion- I The combination of a main shalt, two disconnected pistons, two separate and distinct cylinders in line with each other, in which the pistons work, two concentric )iston-rods sliding one within the other, and two cranks set obliquely to each other on the main shaft, and to which the pistons are connected.
